(54) DEVICE FOR INPUT OF CONTAINERS

IN PIPELINE HYDRAULIC INSTALLATION

I

The invention relates to container hydrotransport of goods through trunk pipelines, namely to devices for introducing containers into the pipeline,

According to the main author. St. No. 749765, a device for introducing containers into the pipeline gi, a1 of the transport installation, is known, comprising a launching chamber with a variable cross section, having an end gate and a feed tray and is connected.

through the valves with the master-.

with a full pipeline, with the feeding tray being mounted with possibility; vertical movement into the launch chamber on the stud at least one power cylinder, the working cavity communicated with the internal cavity of the start chamber, the power cylinder has a piston stroke adjustment mechanism, and a corrugated apron 1} is tightly attached to the end of the feed tray and to the bottom wall of the start chamber.

However, in such a device is not provided control of the launch process the presence of containers inside the container, the camera after entering them into the chamber and the control of the wrcTBHH after the launch operation into the pipeline, which leads to the unreliability of the work of launching the containers into the pipeline.

When containers are introduced into the chamber, one of them may be located at the location of the input lock, and at start-up it may remain in the zone of action of the activation of the back valve, i.e. an emergency situation is created when a valve cannot be fully closed.

In addition, the mechanical action of the valve on the container leads to the destruction of gas, the loss of the transported cargo and the contamination of the pumped oil product, which is also completely dry.

In order to increase the productivity of the pipeline system, one or more pipelines are installed on one pipe-line®. working such devices in connection with which their aychematnegisvy is important, providing the necessary rhythm of work. The goal of 1-1Ebenerates is to increase reliability and automation and complete cycle of work. Delivered uejtb is achieved by the fact that the device for inserting containers into the pipeline of the airconnection installation is equipped with a dead-weight sensor on the lower end wall of the stemless cavity of the power cylinder, a countershaft-mounted counter, a countershaft-mounted telescopic gear, and a tooth-closure-horn-to-empty counter mounted on the outlet of the main pipeline from the start-up chamber of the power cylinder. control device, and the mechanism for adjusting the stroke of the piston contains a lift height gauge tray While the inputs are connected with setpoint sravnen1et. the number of containers and weighing unit associated with the load bearing sensor, the indicator inputs are connected to the weighing unit, the comparison unit and the container counter, the inputs of the control unit are connected to the comparison unit, the container counter and the tray height sensor. The drawing shows a device, a common view with a function / block diagram of automation. The device consists of the launch chamber 1, with a diameter larger than the diameter of the pipeline 2, which is located eccentrically to the chamber 1 with their upper forming parts. In the chamber 1 a sub-tray feed box 3 of the box-shaped forg is installed, on the basis of which it installs the roller conveyors 4, at the bottom chamber 1 is equipped with a power cylinder 5, the rod 6 of which is connected with tray 3. On the lower end wall 7 of the cylinder 5 in the rodless cavity there is a powerful measuring sensor 8, and on the outside of the wall 7 - sensor 9 of the elevation of tray 3, Tsilin The other 5 is equipped with a mechanism for adjusting the stroke of the piston of the power cylinder 5. The lower part of the chamber 1 and the tray 3 are connected by a corrugated apron 11 of; rubber cloth material. The chamber 1 is connected to the flow pipe of the welders 12, the outgoing pipeline 13 and is equipped with valves 14-17. The meter 18 of the containers 19 is installed on the pipeline 2. The functional scheme of the automation consists VI3 of the weighing unit 2O, the comparison unit 21, the setting device 22 of the number of containers in the launch party, the control unit 23. associated with the executing authority of the pushpins 14-17 and the conveyor belt 24 to the display unit 25. In the initial state, the display unit 2.5 shows zero. The operator sets the required number of containers 19 of the batch to be started in the setting unit 22, and using the mechanism 10, the required lifting height of the tray 3. At a signal from the control unit 23, the valve 17 is closed, the valve 16 is opened and the movable conveyor 24 is turned on. At the same time, at the output of the weighing unit 2O, voltage pulses appear, corresponding to the number of containers in tray 3. The pulses arrive at the input of the comparator unit 21 input to the display unit 25. When the number of impulses is on the progress of the comparison block 21 coincides with the number previously set by the operator in the setting unit 22, at the output of the comparison block 21 a voltage pulse appears, which enters the display unit 25 and sets it to zero. The same voltage pulse is fed to the input of the control unit 23, from the output of which a signal is given to stop the conveyor 24, close the filling 16. After closing the valve 16, the signal from the control unit 23 gives permission to open the valve 14, and the pumped liquid is supplied to the chamber 1. The chamber 1 is filled, the pressure in it rises and is supplied through the impulse tubes 26 into the working cavity of the cylinder 5, which ensures the lifting of the tray 3. When the rod mechanism 1O reaches the extreme upper position, the sensor 9 is activated, which through the control unit 23 feeds from the gate to the opening of the valve 17, and containers 19 exit into the main pipeline 2. In the counter 18, which contains the ultrasonic emitters-receivers 27, the number of containers introduced into the pipeline of the batch is set by setting its secondary equipment. When the number of the installed and the number of the passed containers 19 coincides, a voltage pulse appears at the output of the switch 18 through the acoustic path of the emitters-receivers 27, which is supplied to the control unit 23, the output of which gives the command to close the valve 17 and then open the valve 15 and the drainage of the fluid begins. If, for any reason, not all containers 19 of the lot passed the acoustic path of the 2T emitters-receivers. Then the ultrasonic counter 18 does not generate a voltage pulse to the control unit 23, and only records the number of containers passed. Thus, the operator receives data on the number of containers left in the main pipeline. At the end of the drainage, the tray 3 is lowered to its original position and the signal from the output of sensor 9 stops flowing to the control unit 23, and if all containers loaded in the chamber are gone, there is no signal at the output of the weighing unit 2O, and zero is fixed in the control unit 25 camera is empty. The process of launching another batch is similar to that described. If, however, at least one container from the lot remains in the chambers, then by a signal from the weighing unit 20 in the display unit 25 this is recorded with the corresponding figure, and in this case the operator decides. The use of the proposed device makes it possible to monitor and record objects launched into the main pipeline, which allows to automate start-up operations and ensure trouble-free operation of the device, thereby increasing its reliability. 6 6 Claims of invention The device for inserting containers into the pipeline of a hydrotransport unit | St. M 749765, excluding that, in order to increase reliability and automate the full cycle of operation, the device is equipped with a force-measuring sensor, a container counter installed at the outlet of the main pipeline from the camera Zbshkusk, 1M unit, mounted on the lower face wall of the rodless cavity of the power cylinder , the container container base, the comparison unit, the indicator and the control unit associated with the shut-off valves, and the piston stroke adjustment mechanism includes a tray lift height sensor, the inputs of the comparison unit are connected to the unit for setting the number of containers and the weighing unit connected to the load sensor, the inputs of the indicator are connected to the weighing unit, the unit of comparison and the container counting, the inputs for the control unit are connected to the comparator unit, the container counter and the elevator height sensor.
